Only if you hit the same LNS.

Do you need an LNS if you run the network from the home to the core, and don't wholesale? Surely the whole thing is routed? I saw CF as akin to VM. No wholesale going on, no alternative ISPs on the "last mile" network.

Agree. And even if the network is wholesaled City Fibre manage it. They run their own infrastructure but wholesale out through resellers across Openreach/BT Wholesale and don't struggle to give fixed IPv6. It's there for the asking with Aquiss at least - 22 minutes from raising a ticket to confirmation it had been done.

Other ISPs allocate static Ipv6 as the norm and don't make a big song and dance about it.

I think you'll find it's not the "norm". The largest ones (BT, EE, Sky) provide dynamic IPv6 - for the reasons I gave above. Talktalk, Vodafone and Plusnet don't provide IPv6 at all, but if and when they do I would expect them to be dynamic. Mobile networks give dynamic IPv6.

The ones who provide static IPv6 are the more boutique crew, the largest of which is probably Zen. This is market forces in play: there are some people who want this, and there are providers who meet their needs (for a price).

But it does cost them more to do this, in terms of additional equipment and complexity in their network. That's the reason it's not done as standard: ISPs are a low-margin business, and they are not going to spend money implementing a service feature that few will notice. (TBH, most customers won't even notice that they have IPv6).

For those that do provide static IPv6, for the most part they provide static as the norm. Because once you do it, for the economy reasons you mention, it makes sense to do it either for all or for none.

The reason mobile is dynamic is because there is very little in the way of services provided from mobile devices. And what there is, does not need to be synchronous andc could be uploaded to a fixed server. But these days, a modern home often provides services - eg security cameras, device switching, heating adjustment. So it makes sense for fixed customer systems to have a static IP, especially if the other end - a mobile device - is dynamic IP. Or you end up with messy no-ip work-arounds, which are only required under IPv4 due to address shortage and NAT and are completely unnecessary with IPv6.

I'm on Aquiss and it's one of the reasons I chose them. They're definitely in the category of "boutique provider" - they announced reaching 10,000 FTTP customers less than 18 months ago.

You and I are in the (I guess) <5% of users who run servers on our own networks and care about static addressing.

I meant CommunityFibre in my post, and I don't think they have anything to do with CityFibre. One is a direct retail operation running their own network (as are many Alt Nets). The other is attempting to compete with Openreach and offers wholesale products. AAISP for example are able to see via CityFibre.

Openreach and BT wholesale are two different things, however many smaller ISPs may use BT Wholesale to access the Openreach products. Yes, Aquiss is a smaller provider. AAISP can provide service over both Openreach (via BT wholesale I believe) and CityFibre networks.

Only CommunityFibre run services over their fibre.

I suspect CF are trying to stop people running servers, its the only reason to have a dynamic v6 prefix - its that simple,
